Yikes! Don't ever take the radiator cap off when the radiator is hot or even warm. The coolant is under pressure, and comes out quick when you open the radiator.
Also, it's best not to drive too far on an overheated engine, because that can cause internal engine damage that's expensive to fix.
There could be a number of things wrong. The easiest one to check is your coolant level. The operator's manual will give you good instructions on doing this properly, but usually you wait for the engine to be cool, and then you check the level on a reservoir, adding fluid to it if necessary. (not directly into the radiator)
You could also have a blockage or air bubbles in the radiator or other damage that's keeping it from cooling effectively. You may be able to flush your radiator and refill it with coolant. Again, see the owner's manual.
But from your symptoms, it sounds like the fans are having a problem. There should be one or two fans mounted behind your radiator to keep the air moving when the car is idling. The fans, their wiring, or the switches that control them may be faulty.
You can try following the wires from the fans to the wiring harness to make sure they aren't broken, have damaged insulation, or unplugged. But you might need a mechanic to do more advanced troubleshooting.
Also, some models of cars can run their fans even if the ignition is turned off, so be careful when working around the fans; they can turn on unexpectedly.
